Subject: [PATCH 4/7] arm64: dts: qcom: msm8916-samsung-fortuna: Add rt5033 battery

From: Joe Mason <buddyjojo06@...look.com>

Like the Samsung Galaxy A3/A5, the Grand Prime uses a Richtek RT5033 PMIC
as battery fuel gauge, charger, flash LED and for some regulators.
For now, only add the fuel gauge/battery device to the device tree, so we
can check the remaining battery percentage.

The other RT5033 drivers need some more work first before they can be used
properly.
